Product overview
Samsung lists M393A2K43CB2 as a 16GB DDR4 ECC registered RDIMM dual rank x8 288-Pin Server Memory Module (speed grade depends on suffix). Registered, load-reduced and unbuffered modules are not interchangeable, and a board that accepts one will refuse to post on another. This module is ECC. Send the server model and we will check it against the supported-DIMM list before you order.
If the part is wrong for your platform we will say so and suggest the one that is, which is cheaper for both of us than a return.

Questions buyers ask about this part
- Is M393A2K43CB2 genuine and is the warranty intact?
- Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
- Will M393A2K43CB2 work in my server?
- Send the server model and a list of the DIMMs already fitted. Rank, voltage and population order all have to agree, and a module that is electrically compatible can still be unsupported in a given slot. We map the population before you order.
- Do you accept purchase orders and quote at volume?
- Yes. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

Specifying a system, not just the part?
